1 Claim. (01. 87-5) The improved shaving preparation comprising the above mentioned objections by modifying the the present inventionpossesses among other feause of such alkaline substances and by incortures the advantage that no lathering is required. porating therein a plurality of substances hav- The present and almost universal practice in ing local anmsthetic and healing properties.

This use of lather'in shaving provides a v d S t y in e e di ect o wit ut dematerial which combines the properties of softstroying the beneficial properties of'the result ening the hair and furnishes a degree of meing emulsion.

Such preparations therefore belong to the lather type.

deed, most experienced shavers have been obliged In the preferred method of preparing the above 50 to resort to the use of such emollient as lotions mentioned formula the stearic acid and hydrous and skin balms which are commonly referred to lanolin containing 20% water, together with the as after shaving lotions, and which are employed cocoanut oil, are melted together and to this mixfor alleviating the abraded surfaces of the skin. ture is added the concentrated ammonium hy- The improved shaving preparation'overcomes droxide, which contains approximately 25% amll monia. The waxes are then added and heating is continued until the entire mixture is liquefled. The resulting mixture is subsequently removed from the heat and a warm solution of the boricacid in approximately 75 g. of water is added while continuously stirring. At this point or at any point previously, the menthol, camphor and selected perfumes are added in amounts which give the most pleasing effect.

It is to be distinctly understood, however, that the various ingredients comprising the present invention may be mixed in any desired manner, for example, the stearic acid, the hydrous lanolin and the waxes may be previously mixed and melted and ammonium hydroxide and other substances I with it into the skin the antiseptic boric acid.

The cocoanut oil gives a smooth texture to the preparation and serves as a lubricant for the razor blade. The ammonia reacts with the stearic acid to form a small amount of emulsified substance which still further lends smoothness and consistency to the entire mass.

The function of the waxes in the preparation is to form a thin film on the area to be shaved, which film aids in forming a mechanical support to hold the hair upright so that the razor will cut and not pull through the hair. The menthol andcamphor are employed for their local anaesthetic eflect in suflicient quantities to stimulate the nerves by accentuation of the sense of perception of cold. Thus, a cooling and pleasing effect is obtained by the use of these substances. The perfumes are added in small amounts to render a lasting effect that remains on the face long after the shaving operation is completed. The water which-is introduced with the boric acid is essential to the consistency of the cream.

As stated above, the proportions oi. the ingredients, as well as the ingredients themselves, may be varied. For example, instead of using stearic acid for the base, an equivalent amount of a similar fatty acid, such as palmitic acid, may be substituted. Numerous vegetable oilshaving substantially the same melting point as cocoanut oil, may be employed instead of the latter. The

parafiin and spermaceti waxes may be used singly or in combination, or other waxes of approximately the same melting point may be employed. However, for best results the use of spermaceti and paraiiin wax in the proportions named,-

should be adhered to. 'The boric acid may be v.

dispensed with and, if desired, other suitable alkali borates such as potassium or ammonium borate may be used. 1

In place of ammonium hydroxide, there may be employedthe chemical equivalent of one or more derivatives or amines. ployed are discretionary. I v

The resulting preparations can be used if de-' sired by direct application to the face without previous treatment. The resulting shave is easy and nonpulling, leaving the face soft and'smooth. The cream remaining on the face after shaving may, if desired, be rubbed into the skin in order.

that the same may obtain the beneficial properties'of the antiseptic and softening ingredients contained therein. The cream may, however, be

Only insofar as the invention has particularly been pointed out in the accompanying claim, is the same to be limited.

What we claim as new and desire to secure by Letters Patent isz.

A neutral shaving preparation of a latherless I type which consists of a mixture of the following ingredients in substantially the proportion stated,

stearic' acid 11 grams, lanolin 10 grams, cocoanut oil 0.3 gram, concentrated ammonium hydroxide 1.35 grams, parafiln wax 6 grams, spermaceti wax 2 grams, boric acid 1.5 grams, water 75 grams, and having a trace each of menthol, camphor and perfume.
